2x + 4 = x^2 + x - 2
x^2 + x - 2 - 4 - 2x = 0
x^2 - x - 6 = 0
(x - 3)(x + 2) = 0

x - 3 = 0          y = 2x + 4
x = 3               y = 2(3) + 4
                       y = 10

x + 2 = 0          y = 2x + 4
x = -2               y = 2(-2) + 4
                        y = 0

solutions are : (3,10) and (-2,0) <===

You need 3 1/2 cups of flour for each batch of cupcakes. How many whole batches can make if you have 17 cups of flour? Show two
rosijanka [135]

<u>ANSWER:</u>

4 batches of cupcakes can be made.

<u>SOLUTION: </u>

Given, we need 3\frac{1}{2} cups of flour for each batch of cupcakes. And we have 17 cups of flour.

We need to find how many batches can be made.

1st way:

We will get the number of batches when we divide the available cups with cups required for one batch.

Available cups = 17 and required cups for one batch = 3\frac{1}{2} = \frac{7}{2} cups

number of batches = $\frac{17}{\frac{7}{2}}$

$=\frac{17}{1} \times \frac{2}{7}$

$=\frac{34}{7}$ = 4.857

As the number of batches can’t be fraction, we will neglect the fractional part.

2nd way:

Let the number of batches be x.

Then, cups of flour required for batches must be less than available flour

(x)(\frac{7}{2}) < 17

(x)(7) < (2)(17)

7x < 34

x < \frac{34}{7}

x < 4.857

As the number of batches must be an whole number, x becomes 4.

Hence, 4 batches of cupcakes can be made.

Frankie scores a 70% on her math test. The test had 20 questions. How many questions did she get correct?​
ipn [44]

Answer:

14 questions correct

Step-by-step explanation:

x/20 *100 = 70

so x/ 20 = 70/100(0.7)

x/20 = 0.7

x = 0.7*20

x =14

Harper left his house at 9:15 am. He walked 2.5 miles. If harper returned home at 10:00 am, what was his speed in miles per hour
Ksenya-84 [330]

Answer:

3.3 miles per hour. this is because speed is equal to distance travelled divided by time taken. so you calculate how many minutes he spent that is from 9:15 to 10:00 . since you are calculating in miles per hour, you convert the minutes to hours and do the working according to the formula
